Miami Blues (1990)

Real badge. Real gun. Fake cop.

After Junior is released from prison, he plans on starting a new life in Miami. But when he kills a man in the airport, he flees the scene and finds Susie, a mild-mannered prostitute searching for stability. The two opposites become romantically involved, and Junior steals a badge and gun from a veteran detective. Using the officer's identity, Junior embarks on a crime spree and convinces Susie that he is the perfect man.
